- BAG CLOSURE Filed June 20, 1927 ATTORNEYS ?etcnted Dec. 30, 1930 JAMES K. DIAMOND, F GRAND BAIPIDS, MICHIGAN BAG CLOSURE Application filed June 20,

The main object of this invention is to provide an improved bag closure which is effective in closing bags containing heavy materials such as cement, lime and the like, and

also one which is capable of rapid manipulation thereby adapting it for bags requiring rapid opening and closing such as mail bags and bags repeatedly used for transporting various materials.

A further object is to provide a closure having these advantages which may be efi'ectively locked or sealed.

Objects pertaining to details and economies of my invention will appear from the description to follow. The invention is pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, in which Fi 1 is a perspective view of a bag embodying the features of my invention with the bag closed.

Fig. 2 is a fragmentary perspective view of a bag embodying the features of my inventicn with the closure open.

Fig. 3 is an enlarged detail showing the means for supporting the closure upon the bag and the relation of the parts.

Fig. 4-is a detail section on a line corresponding to line 4-4 of Figs. 1 and 3.

Fig. 5 is a fragmentary edge view showing the closure secured by means of a seal of the car seal type.

Fig. 6 is a fragmentary perspective view illustrating the manner of adjusting the bag to a filling spout.

Referring to the drawing, 1 represents a fabric bag open at one end, the opening being provided with beaded edges 2 formed by Q turning the edges over the cords 3 and the inturncd flapportions 4 being disposed on the inner sides of the walls of the bag. These inturned portions are secured by rows of stitching 5 adjacent the beads and adjacent 5 the edge of the flap. i

The tubular closure member 6 has a longitudinal slot 7 of such width asto receive the walls of the be between them, the diameter of the closure ll eing such as .to receive the beaded edges 2 of the bag as shown in Figs? 1927. Serial No. 199,975.

3 and 4. The combined width of these" beaded edges substantially exceeds the width of the slot so that it is impossible for the beads to 1 pass through the slot when the cloure is slipped over the beads with the beads lying side by side.

The closure is slidably supported by the tubular support 8 which has ears 9 lapping upon the sides of the bag and secured by rivets 10 arran ed through the sidewalls as shown in Fi 4. The flaps 4 are of such width that the rivetsv pass therethrough, thereby providing a very secure attachment for the support to the bag.

The closure member is preferably provided with annular beads 11 providing stops adj acent its ends which coact with the support to limit the opening and closing movement of the closure member and retain it in assembled relation to the support.

The closure member is of such length thatwhen closed, its ends project beyond the edge of the bag, its projecting end having a hole 12 therethrough to receive a locking or retaining means such astheseal 13.

When the closure member is in bag closing position it constitutes an effective grip or hand hold by which the bag may be handled.

The bags may be rapidly, opened and closed and may be opened to any extent de- .sired, thus particularly adapting them for attachment to a filling spout, the bag being slipped upon the spout, as 14, and the closure adjusted to clamp or close the bag upon the spout. The closure is manipulated as the bag is withdrawn from the spout so that it is completely closed substantially as soon as it slips from the spout, which is also a feature of advantage.

. Bags embodying my improved closure are adapted for use in various relations as for cement, lime and the like, or where the bag is to contain heavy materials. The structure is also desirable for use in bags where it is necessary to quickly open and close the bags as in mail bags and the like.

p I have, however, only illustrated my improvements as adapted to a plain type of bag as it is believed this disclosure will enable Walls of the bag ajacent its said beaded edges,

a tubular support secured to said bag at one end of its opening, said closure being slidable in said support and provided with stops adjacent its ends coacting with said support,

the other end of said closure pro'ecting beyond the bag and being perforate to receive a lock or seal.

2. In a bag closure, the combination of a bag provided with beaded edges, a tubuiar closure member telescopingiy associated with said beaded edges and slotted to receive the walls of the bag adjacent its beaded edges,

and a tubular support secured to said bag at one end of its opening, said closure being slidable in said support.

. 3. In a bag closure, the combination of a bag having an o ening provided with beaded edges, a lon itucfinally slotted tubular closure telescopingfy engaging the said beaded edges,

a supporting sleeve for said closure member secured to said bag, said closure member being provided with stops coacting with said sleeve, and means for retaining said closure member in bag closing position.

4.- In a bag closure, the combination of a bag' having an opening provided with beaded edges, a lon itudinallyslotted tubular closure telescoping y engaging the said beaded edes, and a supporting sleeve for said closure member secured to said bag, said closure member being provided with a stop coacting with said sleeve.

5. In a bag closure, the combination of a bag having an opening provided with beaded edges, a longitudinally slotted tubular closure telescopingly engaging the said beaded edes, and a supporting sleeve for said closure member secured to said bag.

6. In a structure of the class described, the combination with a bag provided with thickened to edges, a tubular closure member longitu inally slotted to receive the walls of the bag and telescopingly embrace the said thickened edges thereof, and a tubular support for said closure member provided with attaching ears lapped upon the opposed walls of the bag and secured thereto to slidably support the closure member in position to telescopingly embrace the said top edges of said bag.

7. In a structure of the class described, the combination with a bag provided with thickened top edges, a tubular closure member longitudinally slotted to receive the walls of the bag and telescopingly embrace the said my hand.

ber secured to said bag to slidably support the closure member in position to telescopijngly embrace the said top edges of said In witness whereof I have hereunto set J AMES K. DIAMOND.
